The patent filed by InterDigital Inc. describes a method and system for transmitting and receiving signals using low density parity check (LDPC) codes. The method involves transmitting a first signal with systematic and parity bits, receiving an indication of incorrect reception, and then transmitting a second signal with LDPC bits based on a specific LDPC base graph. The system includes a wireless transmit/receive unit (WTRU) with a transmitter, receiver, and encoder/decoder to implement this method.
The claims detail various aspects of the method and system, such as the inclusion of other systematic and parity bits in the second signal, combining systematic and parity bits, encoding based on the LDPC base graph, and the ability to combine the first and second signals for successful data reception. The claims also cover scenarios where the second signal may include some or none of the first LDPC bits, the use of incremental redundancy for signal combination, and the application of the method and system in both user equipment (UE) and base stations. Overall, the patent focuses on improving signal transmission and reception efficiency using LDPC coding techniques in wireless communication systems.
